Hi

I don't know wheather this topic belongs here. However since this is a pocket pc phone edition forum I thought it better to post this here so that those of you undergoing trauma over configuring the bluetooth dongle are spared the agony. Well to start with the device I have is an i-mate with windows pocket pc 2003 running on it. Recently I acquired Widcom USB bluetooth dongle. Configuring it was a nightmare. Thanks to David who had given a post elsewhere part of the problem was solved.

The issue is when configuring bluetooth with windows XP you need to emulate the bluetooth connectivity as a serial port. That's how active synch sees it. If by mistake one ends up installing com ports greater than 9, active synch throws in the towel and you will never know what happened. This is because of a bug in active sych I am told. Even active synch 3.8 is no good in this regard.

Now the second bug is that there is no way you can retrieve the ports you have configured earlier. It goes on incrimenting and by the time you end up with com44 your face would have gone as blue as the light in the dongle or pda.

So as per David there is way to delete these 'Ghost' ports by making these Ghosts visible by setting the following environment variable C:>set DEVMGR_SHOW_NONPRESENT_DEVICES=1
Then in the device manger Checking View->Show Hidden Devices. This should bring up all the Ghosts out.

However in my case this did not happen. Only two additional ports were visible. These were port 15 and 17. Rest managed to remain hidden. Now how do we know that?

Well here is what you do. In the device manager open the branch Ports-Right click on communication port (COM1) -> Properties and then click on port setting tab. Click on Advanced
At the bottom you see a drop down box called com port number. When you open this you will be surprised to see all those mystery com port marked as "(in use)". So you are stuck as to what to do with these. HERE IS THE TRICK

TRY TO RENAME COM1 WITH ANY OF THESE PORTS IN USE. CLICK OK. COME BACK AND RENAME THE PORT BACK TO COM1. VOILA !!! :) THE PREVIOUS PORT IS NOW FREE. REPEAT THIS TILL YOU HAVE ALL THE UNWANTED PORTS FREE. REBOOT YOUR MACHINE AND COOLY INSTALL THE WIDCOM DRIVER OR WHATEVER. YOU WILL HAVE PORTS LESS THAN THE MAGIC NUMBER 10 AND EVERYTHING STARTS WORKING BEAUTIFULLY. BILL GATES ACTIVE SYNCH IS ALSO VERY HAPPY.

Well that's it. DOES ANYONE KNOW WHERE THIS COM PORT DATABASE IS KEPT?. It is not in the registry. Does anyone know how to connect your PC to the internet using the wireless modem emulator in the PPC and bluetooth?? Pse help

ok so i followed the bt guide for my phone (imate jam aka xda aka a million other names) but when it comes to the part when you select start on the phone and a dialogue box appears please start bonding with other bluetooth device which supports serial port or "activesync profile as your activesync partner" then you press ok and i get something different from whats shown in the guide, it just goes to the bluetooth connections as if you would go to settings->connections->bluetooth i dont know what to do from there, i've tried several things but still cant "bond" with my pc.

You don't need wmodem when using Bluetooth. From your PC or other device look for a service called DUN (Dial-Up Networking) if you want to use the mobile device for connection to a cellular network.

Here is what I am trying to do. I have this imate pocket pc phone editiion one of the earlier version of the imate device. The details of the device are as under:-

ROM VERSION 1.66.00WWWE
ROME DATE 02/20/04
RADIO VERSION 1.10.00
PROTOCOL 1337.18
EXTROM VERSION 1.66.131

iNTEL(R) PXA263
SPEED 400MHZ
FLASH CHIP TYPE 28F128K3

Microsoft Pocket PC ver 4.20.0(Build 13252)

Well I am trying to connect my PC/Laptop having X-micro bluetooth adapter connect to the internet through my device. Same way you would do when the device is in cradle with wmodem on with connection type USB. Only instead of USB I want to use the bluetooth connection type. So my device acts as a modem for my PC/Laptop connecting through bluetooth.

When I choose bluetooth as a connection type nothing happens. I have installed the bluetooth modem on the PC, the driver having been supplied by widcomm. In fact this got configured when I was configuring DUN on the client tab of the widcomm software.

1. I am not able to figure out what is wrong. Am I missing something here?

2. Does my ROM need an update?, if yes, how do I go about doing it

3. Can I upgrade to Windows Mobile 2003 Second Edition if so how?

4. I saw a picture posted by you showing the wmodem screen with connection type as bluetooth and all lights on. In my case nothing happens.

5. is it the bluetooth stack that needs update?

Will be greatful for any help. Thank you

FF

Just check that the port marked as Active Synch in the Bluetooth applet Advanced Configuration tab->Local services is the same as the one indicated in the Active Synch Connection Settings.

You don't need WMODEM for this. Just make sure the computer and i-mate are paired and follow these instructions on your PC. No configuration is needed on your Pocket PC.

Mauricio,

Thanks for the tut. But in my case it is just not working. My device is paired with the computer. may be u can figure out something. When I run diagnostic on the installed modem it comes out ok.
all goes well till it says "Dialing *99***1#. This screen hangs for 3 to 4minutes and I get an error message saying it has timed out. On the device just about nothing. GPRS on the device and through USB-WMODEM is working fine.

You have to try other configurations then.

First are you 100% sure you followed the article I've pointed out? No need to install modem or anything!

Next, perhaps you have to use other configuration? Try *99# first. Then try *99***[x]# where [x] is another number... If this fails then perhaps you have to configure an init string on your connection configuration on your computer to send the full APN configuration to the Pocket PC, as in +CGDCONT="1",,"[apn]" where [apn] is your operator's APN?

Mauricio,

I had followed the steps ditto. I am using the SSA profile which was configured by the software. GPRS is configured properly and the number is *99***1#.

A connection is made between the PC and the PPC since the icons go green. Once it starts dialling it goes into a limbo. When configuring the SSA profile only, it installs a Widcomm Bluetooth modem which can be seen in the phone and modem applet in control panel. I have some images which I don't how to upload which would make things clearer. My APN is "airtelgprs.com". I am using the following in the extra string setting in the advanced tab of the bluetooth connection setting.

AT+CGDCONT=1,"IP","airtelgprs.com","",0,0

Anyway what does the Conncection Type Bluetooth do in the WMODEM utility? The point is GPRS is accessible both through the device alone and on the PC through the USB cable with WMODEM enabled. Why is it not connecting through the bluetooth is the question I have tried all combinations. Pse do something

I have X-Micro Bluetooth Dongle USB 2 which is a class 2 bluetooth device. The software that came with it installs it as Broadcom USB Bluetooth Device using Widcomm drivers.
